CAS-led researchers developed a peak-selective passivation strategy using aluminum oxide nanocoating to solve leakage issues in pyramid-textured silicon for perovskite–silicon tandem cells. The method is compatible with existing silicon manufacturing and enables high-efficiency, stable devices reaching around 33% efficiency.

Solar cells, devices that can convert sunlight into electricity, are now widely used in many countries and are contributing to the reduction of greenhouse gas emissions on Earth.…
